Linux HOW-TO setup XBMC and Linux with correct resolution (xorg.conf)

finite3 · 2010-01-30 01:59

Yes kindof.
You don't need edid to do this.
You can find the specs for your tv (sync rates etc) in the manual or (hopefully) on the web.
Try this: http://www.mythtv.org/wiki/Working_with_Modelines
Note I used gtf to calculate modelines for specific resolutions instead.
Or you can use online modeline calculators.

If you think faulty edid is tripping you up even though you have hard-set modelines, then make sure your xorg.conf has

Code:

Option          "ModeValidation"        "NoEdidModes"

and

Code:

    Option         "ExactModeTimingsDVI" "true

in it.

Check http://http.download.nvidia.com/XFree86/...dix-b.html for more xorg.conf info & explanations about options

Or just give in and give the sample xorg.conf a go.

Hi guys,

When I try to find the modelines, this is one of the numerous Validation sections:

Code:

[Validating Mode "1920x1080":

(II) Feb 04 19:40:17 NVIDIA(0):     1920 x 1080 @ 60 Hz

(WW) Feb 04 19:40:17 NVIDIA(0):     EDID are not allowed.

The only valid 1920x1080 mode shown is this:

Code:

[Validating Mode "1920x1080":

(II) Feb 04 19:40:17 NVIDIA(0):     1920 x 1080 @ 60 Hz

(II) Feb 04 19:40:17 NVIDIA(0):       HSyncEnd, HTotal : 2000, 2080

(II) Feb 04 19:40:17 NVIDIA(0):       VRes, VSyncStart : 1080, 1083

(II) Feb 04 19:40:17 NVIDIA(0):       VSyncEnd, VTotal : 1088, 1111

(II) Feb 04 19:40:17 NVIDIA(0):       H/V Polarity     : +/-

(II) Feb 04 19:40:17 NVIDIA(GPU-0):     BestFit Scaled and BestFit AspectScaled are identical;

(II) Feb 04 19:40:17 NVIDIA(GPU-0):         collapsing BestFit AspectScaled.

(II) Feb 04 19:40:17 NVIDIA(GPU-0):     BestFit Centered and BestFit Scaled are identical;

(II) Feb 04 19:40:17 NVIDIA(GPU-0):         collapsing BestFit Scaled.

(II) Feb 04 19:40:17 NVIDIA(GPU-0):     BestFit Centered         1920x1080

(II) Feb 04 19:40:17 NVIDIA(GPU-0):       Horizontal Taps        0

(II) Feb 04 19:40:17 NVIDIA(GPU-0):       Vertical Taps          0

(II) Feb 04 19:40:17 NVIDIA(GPU-0):       Base SuperSample       1

(II) Feb 04 19:40:17 NVIDIA(GPU-0):       Base Depth             32

(II) Feb 04 19:40:17 NVIDIA(GPU-0):       Distributed Rendering  1

(II) Feb 04 19:40:17 NVIDIA(GPU-0):       Overlay Depth          32

(II) Feb 04 19:40:17 NVIDIA(0):     Mode is valid.

So, my modeline is

Code:

Modeline "1920x1080" 138.50 1920 1968 2000 2080 1080 1083 1088 1111 +hsync +vsync

When I try an insert that modeline, along with all the other recommendations in the xorg.conf file, XBMC never comes up. All I get is a blank screen. Removing the modifcations gives me a working display, but I have jitter issues.

Comments?

Kid

@kid,

Let us see your xorg.conf and 2nd'ly what does your /var/log/Xorg.0.log say after you boot up with the new mode line. There should be an error. Some has to be up as it at least should boot with a xorg error or low res issue I would think unless you are on Live. That why it is nice to have a desktop sometimes at least xubuntu or xfce4 work great and are light anyhow that is another topic.

regards,

Dave

@Kid,

Did you set the frequecies of your TV in the monitor section that were reported from the xlog.txt file you created and finally it looks the computer is fine - the TV is showing you a black screen which means your line is likely out of range, if there are no errors in the xorg.0.log file it is loaded fine by the look of it.

get rid of the first option UseEdidFreq this is taken care of by the No Edid Modes in the other section. reboot and check.

you can also try disabling DPMS so in the option line after dpms add "false"

reboot and check

Regards,

Dave

kidproquo · 2010-02-06 19:30

Dave,
Yes those frequency ranges are from the xlog.txt file. I tried setting DPMS to "False". No change.

angedelamort · 2010-02-07 00:26

The guide is quite good and I did everything and my system (Acer Revo R3610) seems to boot fine. I've got Live Version installed on my HD.

So, my problem is simple: I choose the "1920x1080" resolution and my TV still tells me that it's in 1080i. So, I try to find in the list: 1080p 60Hz but it seems that it's not there. So I suppose there is another file we need to edit in xbmc? If yes I would like to know which one and if no, what did I need to do.

Thanks in advance.

--- edit #1 ---

Where I take the information for the ModelLine I'm got this message at the end:

Code:

Mode is rejected: Modes from the TSB-TV (DFP-0)'s EDID are not allowed.

--- edit #2 ---
After some googling, I came across the nvidia documentation about the EDID. So I decided to add in the monitor section the following option:

Code:

Option "UseEdid" "FALSE"

Conclusion, still no change in my problem. It's always impossible to choose my user created resolution "1920x1080@60p" from the list of xbmc.

Have you checked the Myth modeline db to see if your TV is listed in there at all. google myth modeline db, there is a vast list of devices.

Are you plugged directly into the TV and not through an amp.

Regards,

Dave

angedelamort · 2010-02-07 03:54

I found this thread and I was able to play with the different values of the xorg.conf. It seems that it makes it works for me. The problem seems to be the TV and the default "auto-configuration".

But I had to add this line as well or it was still in 1080i:

Code:

Option         "ExactModeTimingsDVI" "TRUE"

I'm not really familiar with the display drivers nomenclature and haven't really touched Linux for more than 10 years, but as a programmer I found that when you have a problem, it's still the same as 10 years ago, it takes age to figure out. Thanks to the internet now with all the different forums.
